3. OPERATION
3.27 DRUM/SCRAPPERS
Clean and inspect daily to prevent excess mud and
debris from building up. Replace if missing or worn.
Pad drum scrappers are adjustable, see Maintenance
section.
3.28 CLEANING
DIRT AND MUD BUILT UP WILL REDUCE
MACHINE PERFORMANCE AND/OR CAUSE
FAILURES.
Use pressurized water to remove dirt and mud. Clean
and inspect entire machine daily. Use extra care when
cleaning radiator and oil cooler.
When cleaning machine, caution should be used
around regulator area. Direct spraying of the
regulator is not good. (Regulator should be covered
or protected if direct spraying will happen).
Excessive water pressure may also loosen wire
connections or start terminals corroding. After
cleaning, all terminals should be dried if wet and
connections checked for proper seating.
3.29 ECCENTRICS
When vibratory compaction is necessary, engage
eccentrics by pushing the vibration switch to the ON
position. For best performance run engine at full
rpm. The eccentrics should be turned off whenever
the roller is stopped or stopped to change direction.
Do not run the eccentric on any non-yielding surface
such as concrete or aged asphalt.
3.30 COMPACTION TIPS
Avoid sharp turns, steer gradually. If articulation is a
new concept, we suggest the operator take 20 minutes
or so to get used to the feel of the unit.
Recommended compaction speed should be at
3 m.p.h. or less to achieve a uniform compaction.
WARNING
DO NOT ARTICULATE ON GRADES LARGER
THAN 15, ROLLER MAY TIP OVER.
DO NOT OPERATE ACROSS THE SIDES OF
HILLS, ROLLER MAY TIP OVER.
DO NOT OPERATE AT THE EDGE OF MATS OR
ROADS, ROLLER MAY TIP OVER.
DO NOT STAND, ALWAYS WEAR SEAT BELT.
3.31 TIE DOWNS
TIE DOWNS ARE NOT INTENDED FOR LIFTING
PURPOSES.
Equipment is equipped with front and rear tie down
rings for shipping purposes. Use only these tie downs
to secure unit.
3.32 TOWING (BYPASS)
NEVER PUSH OR PULL THE ROLLER WITH THE
ENGINE OFF. WHEN ENGINE IS NOT RUNNING,
THE BRAKE IS APPLIED. WHEN THE ENGINE
IS RUNNING AND THE FORWARD/REVERSE
LEVER IS IN NEUTRAL, THE BRAKE WILL
APPLY WITHIN 2 SECONDS.
In an emergency or during a breakdown, it may be
necessary or desirable to tow the roller. This may be
accomplished by mechanically releasing the brake and
bypassing the transmission pump. If these procedures
are followed carefully, the roller may be moved short
distances at LOW speed without running the engine.
The brake is located in the front wheel motor, which
drives the drum of the roller. There is an access hole in
the front frame to assist in releasing the brake. Refer to
the Drum Assembly #39 22770 Kit Bypass to identify
these parts. The threaded hole in the center of the
wheel motor requires a M12 bolt long enough to extend
beyond the frame when fully engaged. A bolt, washer,
and nut is included in a separate package for this
